Republicans gained at least 60 House seats in the Nov. 2 election, but they are positioned to win more. While Democratic incumbents hold leads in two of the six still-contested races, they trail in four others, with thousands of ballots still to be counted.

The total of unresolved races dropped from seven to six on Tuesday when Democratic Rep. Melissa Bean conceded to Republican Joe Walsh. Bean had ousted Republican veteran Phil Crane in 2004 and was seeking her fourth term.

Here is POLITICO's list of House undecided races:
